About this 1ct lab-grown asscher diamond

This 1ct lab-grown asscher sits in the classic one-carat band, graded D colour (colourless) and IF clarity (flawless or internally-flawless), with a standard cut grade and certified by IGI LG671413334 or 671413334. Listed at 23 retailers as of November 4, 2026, with prices from $679 to $3,280, a $2,601 spread on the same certified stone. MOH London lists it at $3,280. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
